1 The present invention relates to printing machines, and an object thereof is toimprove that type designed for writing on checks and other negotiable instruments, Another ob j'ect of the invention is to provide anim proved platen Operating mechanism. 1 Still another object of the invention is to provide a feeding device having a feeding mechanism in which a single ratcheflwheelis operated in upon by two platen operating mechanisms.

A further object of theinvention is to provide a platen operating mechanism having a positive and an elasticconnection witha member which operates apawl in thefeeding.

mechanism of the feeding device] iinother and further object of the invention is to pro vide a novel stop for the feeding device through which the latter may be stopped to position the check at the-beginning of the date line or at the beginning of; the line for the payees name orthe amount; A still further object of the invention is to provide a 7 locking mechanisml for theprinting member having a resilient connection w th theplaten 2 operating mechanism so that said locking device will yield with reference to the platen operating mechanism to prevent the breaking oisparts in the event that the printing me nheris not positionedproperly with reference tothe locking device. "Still another objectof theinvention is to associate with the check .writing machine, a. dating device ofnovel construction. S till further and another ob- ..I ject of theinvention is to provide a novel mounting for the inking meansoi the print ing member of the dating device so that the inking roller travels over; the pr ntlng de-. v ce as the latter moves toward its platen.

Some of such points are at the beginning of each line on the check and also at thebe'ginning of the amount which is written innumbersad acent the end 15 bar or member 120 which is mounted in the channelled guide 90 adjacent one sidewall of the channel and is guided by such guide wall through theprovision of three inclined slots 121- in the side wall and pins 122 projecting from the stop barand operating-in the ln-.

clined slots. This stop bar is also guidedby two projections123 and 124 on the bottom of the channel cooperatingwith the otherside of the bar 120-. The projection 123 also serves as an anchor for the spring 125 which is secured at its other end to a projection 126 on the bar 120. Normally this spring holds the bar againstthe bottom of the channel or in its'upper position with thepins 122 at the upper ends of the slots. 1 This bar carries two stops 127 and 128 which are in the form of machine screws adapted to be fitted respectively into any one of the two longitudinally extending series of openings129 and 130 in order that to provide for the adjustment of the stops 127 and 128. These stops are adapted to cooperate with an;abutment131 on the carrier 91 whenthe'bar 120 is depressed or lowered Thestop127is employed for stepping the outward movement of the workfeeding device 38 so that itholds the check at thebeginning of the. line in which isto be written the amount in numbersadjacent the end"of':the "amount line, whereas, the stop 128 i's'employed when it is desiredto stop the outwardfmovementof the "work feeding device at the beginning of the amount line. or

By pressingtogether the finger pieces 132 .and 133, the bar120 1s moved againsttheaction of the: spring125,

to project the stopsfi127wand 128 so as to engagethe abutment 131 onthe'carriage 91. As

so'onas the finger pieces are released, the spring moves the'bar 120 upwardly and away from stop position.

4 While the machine can be employed for datingthechechfitis preferred to use in connection therewith the 1 dating mechanism and to this end, thework support 7 (see Figs. 19 to 23 inclusive) is provided-to one side of the overhanging frame with a yielding platen 134 in the form of a rubber strip resting upon a depressed'portion 135 of the feed plate7 and having slits 136 at oppositeends through which the ends of the platen strip 134 are passed. Above the platen is mounted the date dog 144 is pressed toward its wheel 143 by a spring 146. Also mounted to turn onthe shaft 145 aretwo arms or levers 147 each of which has a finger piece 148 arranged on the outside of the supporting member 142:1 On'each arm 147 is pivoted a pawl 149 at 150 and withthis pawl engages one arm 151 of a two armed spring mounted on the shaft 145 and abutting the supporting member at 151?. The pawls 149 engage the toothed wheels 143 of the printing members 138 and 139 so that by pressing on either finger piece 148 one of the wheels138 or 139 may be turned one step. Thewheels 138 and 139 print the characters for'the date of the month, whereas, the wheel 137 prints an abbreviation of the name of the month and the wheel 140 prints the last two characters in the year. The wheels 137 and 140 being required to be shifted only infrequently are moved by hand but the wheels 138 and 139 which require more frequent shifting are moved through the finger pieces 148. The carrier 142 for the printing members of the dating mechanism, is in this instance, pivoted at 152 to a bracket 153 which is adjustably secured by bolts 154 to the side of the upper frame member of the machine, in such a position that when the carrier 142 is swung downwardly on its pivot 152, the printing members will print on a check arranged on the platen 134.

With the end in view of inking the dating stamp, an inking device is provided, comprising, in thisinstance, a roller 155 journalled in the housing 156 which is pivoted at 157 to an arm 158 projected from the bracket 153 through a bifurcation in the printing carrier 142. This pivot 157 is eccentric to the pivot 152ofthe housing 156 and a spring .159 acts on the housing 156 to hold theroller against the printingwheels and the pivoted carrier 142 against the cushion 160 on the arm 158.

To effect the printing, pressure is applied to point and thereafter shi t out of the path of j such characters so that when the characters strike the platen, the, inkingroller and its housing will lie to one sideofthe printing point With the release of the carrier 142, the spring 159 presses upwardly on the housing 156 and, through the roller 155,'presses the carrier 142 back to its normal position against the cushioned stop 160. j What I claim as my invention and desire to secure by Letters Patent is:
